CHARLES GARBE, OF PARIS, FRANCE.

DISTRIBUTING-VALVE.

Application filed November 25, 1912. Serial No. 733J163.

To all whom it may concern Be it known that I, CHARLES GARBE, citizen ofthe French Republic, residing at Paris, Department of the Seine,inFrance,

have invented certain new and useful Improvements in and Relating toDistributing- Valves; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention relates to a type of distributing valves for gas; andsteam engines, its chief feature being that it is'highly gas orsteamtight and yet does not comprise any adjustable parts.

The movable part of the valve, which is driven in any suitable manner,comprises a certain number of blades arranged at right angles to thedirection of the passing gases and engaging with corresponding parallelpartitions disposed in the valve casing. A tight joint is obtained owingto the multiplicity of fixed and movable blades yet without it beingnecessary to adjust the movable "nart within the fixed part.

Similar characters of reference designate corresponding parts throughoutthe diii'erent figures of the drawings.

In the accompanying drawings: Figure 1 is a sectional view of a valveaccording to the invention and towhich a rectilinear alternative motionis communicated. Fig. 2 is a section on line AA of Fig. 1. Fig. 3 is aview of a continuously rotating valve. Fig. at is a section on line BBof Fig. 3.

Fig. 5 is a view of a valve which receives an alternating rotativemotion. Fig. 6 is a section on line CC of Fig. 5. Fig. 7 represents amodification of the invention. Fig. 8 is a section on line AA of Fig. 7Figs.

.9 and 10 represent constructional details;

Fig. 11 represents another modification.

The exhaust valve shown in Figs. 1 and 2 comprises a chamber 1communicating on one side, with the cylinder through the port 2, and onthe other side, with the exhaust, through the port 3. Several parallelpartitions 4 are so arranged in the chamber 1 as to divide it in acertain number of compartments; the partitions being separated from eachother by means of spacing pieces 5 and the whole is held together bybolts 6 and nuts 7.

The blades 8 fixed on the movable part rest on the correspondingpartitions Specification of Letters Patent.

Patented J an. 5, 1915..

These blades are also separated from each other by spacing pieces 9 andthe Whole held together by any suitable means. Blades and spacing piecesare mounted upon a head 10 sliding in a chamber 11. In the shut-oilposition, it forms a tight jointeby abutting against the partitions 4and also against "the spacing piece 12 which stops its upward.

movement. The head 10 is integral with a rod 13 which slides in a guide14. The rod 13 receives an alternating rectilinear movement from anappropriate device, for instance, from a rotating cam which liftsintermittently a rod 24 and which communicates its movement to the rod13b means of the spring 25. The return or opening movement of the valveis obtained by means of a spring 26, one end of which rests on theguide14 and the other, on a collar 27 integral with the rod 13.

Owing to the peculiar arrangement of the partitions 4 and the blades 8,the gases which would traverse the valve inits shutoil position, wouldhave to travel along a very narrow, long and sinuous path. Consequentlythese gases would expand and lose some time in passing from onecompartment into the next one; it suliices therefore, to provide asufiicient number of compartments to insure a gastight joint during thenecessary time, 2'. 6. one revolution of the motor. It must be remarkedthat a more certain gastight joint will be obtained if, by anappropriate device or simply by applying steam pressure, some of theblades 8 are applied against the partitions ii When the valve is in itsopen position so as to permit of the free passage of gases from port 2to port 3, these gases traverse a wide and straight openingand there isnothing to it favors cooling, especially if the dZEflVl-lll air iscompelled to travel over these Iibn by means of a suitable piping.

The invention can be easii continuously rotating v prises a chamber 1, Fi

gases will naturally be of greater orderto avoid leakages in thebearings, the

steam-side part of the shaft will be providedwith packing rings.

The ports 2; and 3 of the chamber 1, communicate with the cylinder andthe exhaust, respectively. The partitions 4 have openings in line withand of the same size as the ports while the blades 8 possess wider holes16. The shaft 15 revolves at a suitable speed so as to produce theexhaust at the required moment, for instance, in the case of a fourcycle motor, the said shaft will revolve at half the speed of thecrankshaft.

The bearings 22 and 23 can also take the place of stops so as to keepthe blades 8 within the spaces between the partitions 4 and prevent anycontact thereof; the gastightness being obtained by means of the greatnumber of compartments arranged in series. If, on the other hand, thebearings are not arranged so as to act as stops, the blades 8 will bepressed onto the partitions 4 by steam or gas pressure and theirresistance to the passage of gases will b more efficient. I

Figs. 5 and 6 representa similar device but recelvmg an alternatingcircular movement. The movable part of the valve con-' sists of blades 8mounted on the shaft 15. These blades occupy only a part of the lengthof chamber 1 so as to be able to open ports 2 and 3. The shaft 15,pivoting on a spindle 17 which is fixed on the cylinder in any suitablemanner, is continuously rocked by means of a lever 18 and a rod 20.

Figs. 7 to 10 represent a modification of the invention in which onevalve insures both admission and exhaust and is mounted directly on thecylinder. The valve shown in Figs. 7 and 8, comprises a chamber 1fol-min a cylinder cover and flush with the water ]acket 33. Thischamber comprises partitions 4 kept separated by spacing rings 5. Thewhole is fixed on the water jacket by means of bolts 6 and nuts 7. Ports2 and 3 have been bored in the walls of the chamber 1, the formercommunicating with the interior of the cylinder 38 by a conduit 29 andthe latter with theexhaust by tubing 12. Orifices 34 in line with ports2 and 3 have been drilled in the partitions a as well asorifices 35,both being equidistant from the center but about 90 apart. The openingsserve for the admission of the gas mixture which comes from thecarbureter.

a shaft 15 turning'freely in a bearing 22 and pivoted on a spindle 17which screws at 41 into the cylinder head.

It is evident that the spindle 17 instead of" being in the .axis of thecylinder could be parallel or slanting in reference to it.

Every one of the blades 8 is perforated at 16 and can thus opensuccessively the open? ings 3 1 and 35 of the partitions 4.

The valve is driven by a worm wheel 30 mounted on shaft 15 and engagingwith a.

worm 31 mounted on the secondary shaft 32.' This shaft is mechanicallyconnected to the crankshaft and is driven at half of its speed. In thismanner, the movable part of the valve uncovers successively theadmission and exhaust orifices and insures, byitself, the completedistribution of the motoraccording to the four cycle principle. Thedistributing can be changed by varying the. size and angular distanceofthe openings 15, 34. and 35. A,

The use of this system of distribution'permits of considerablysimplifyingthe con struction of the cylinder; consequently ribs 40 canbe cast on the whole or on a pa'rt of the cylinder, said ribs extendinginto the intea rior of the water-jacket, increase the contact surface ofmetal and water and thus in sure a better cooling of the cylinder and ofthe piston.

Instead of arranging the spacing rings in. the manner shown in Fig. 7they could reach the edge of the blades as shown in Fig. 1, in thelatter case, however, the rings would have to be drilled in line withthe orifices 16 of the blades 8.

The valve can also be made of one piece '.v

of metal in which slots have been milled or cut for the reception of thepartitions of the fixed part.

Instead of admitting and exhausting thecharge through the same orifice,each blade 8 can be drilled in two points so that. there will be oneorifice for the admission and one for the exhaust. These two orificeswill have to be at a certain angular distance just as it is in the caseof the orifices 34 and 3.5 of the partitions 4.

Figs. 9 and 10 show two devices to impede the progress of gases into theinterior of the distributor. In the device shown in Fig. 9, the lowestblade 8 of the valve has been provided with any desired number ofcircular ribs 36 engaging circular slots in the lower part 37 of thechamber of the valve. Thus a perfect gastightness is obtained. The sameresult could be obtained with the device shown in Fig. 10; in this caseboth the lowest blade 8 and the lower part 37 of the chamber areprovided with similar circular slots into which fits a circular ring 39so as to avoid leakage. The devices shown in Figs. 9 and 10 can, ifnecessary, be applied to more than one blade.

Fig. 11 represents yet another modification of the invention in the caseit is applied to a rotary motor in which the crankshaft is stationaryand the cylinders rotate.

The explosive charge is admitted through the interior 50 of thecrankshaft 46 which is provided with an orifice 49 communicating with anannular chamber 48 made in the crank casing l7. Said chamber 4:800.nmunicates with the valve casing by a pipe s 3. The valve is drivenat the same speed as the crankshaft for one port serves for both theadmission and the exhaust; the driving being effected by means ofconical gears 4% and 45, rod 32 and gears-30 and 31. It must be. noted,however that in the last case all the moving parfs have a continuouslyrotating movement.

It is quite evident that the invention is not limited to the devicesrepresented in the drawings and that it may be applied to differenttypes of distributors whether they are fixed to the cylinder itself orto its casing or whether they are designed for the admission or theexhaust.

The invention greatly simplifiesthe construction of valves for itpermits of the use of rough cut pieces which move freely in suitablegastightness.
